Severe Acute Malnutrition (SAM) is responsible for between 1–2 million preventable deaths every year and affects around 17 million children under five. Community based Management of Acute Malnutrition (CMAM) is a proven approach to identify and treat SAM cases. However its effectiveness is limited if treatment protocols are not followed and data is unreliable. A mobile health (mHealth) application was developed and piloted in five countries by World Vision, Dimagi, Save the Children and International Medical Corps (IMC) to help health workers follow treatment protocol and generate accurate and timely data to respond to changes in caseloads.
